SARS and its staff being not so helpful to direct or assist people

I filled via efiling and in branch and my experience was so horrible at the Bellville branch since i got there 7h00 the morning when the first lady directed me to the wrong queue after only being helped only at 16h15 to say i'm in the wrong line and i should come back the next day and when i explained to her my efiling wouldn't except my affidavit to upload , and when i speak to another consultant he says the affidavit is not valid . I then spent an hour on the telephone the next day explaining that i went to the branch with the document to state that the company i had worked for has liquidated and the employer never submitted . Lastly i discover after SARS had to pay me out that i had to pay them an amount . Please can someone just help me as i am unable to get off from work and the deadline has passed already for in branch
